Characteristics of Micas from Sericitolite of the Gongpoquan and Baishantang Deposits, Beishan Area by Scanning Electron Microscope, X-ray Diffraction and Electron Microprobe Analyses

Yankuang ceshi, 2016
The phyllic alteration zone is regarded as one of the most important near-surface markers in mineral exploration of porphyry deposits. The Gongpoquan and Baishantang copper deposits are two typical porphyry deposits in the Beishan metallogenic belt.

Controls on the formation of porphyry Mo deposits: Insights from porphyry (-skarn) Mo deposits in northeastern China

American Mineralogist, 2022
AbstractPorphyry Mo deposits have traditionally been classified into two major classes, arc-related and Climax-type, based on the tectonic setting and chemistry of associated intrusions. Although there is a consensus that porphyry Mo systems were formed by the optimal coincidence of geological processes operating at different scales, it is unclear what

Early cretaceous molybdenum-bearing felsic magmatic rocks in the tongmushan district, northern great Xing’an range: implications for mesozoic porphyry metallogenesis

Frontiers in Earth Science
The Nenjiang-Heihe metallogenic belt of the northern Great Xing’an Range is renowned for Mesozoic epithermal Au deposits, however, apart from the Duobaoshan and Tongshan super-large porphyry deposits in the Paleozoic, no superlarge porphyry copper ...

Supergiant porphyry copper deposits are failed large eruptions

Communications Earth & Environment, 2022
Monte Carlo-based mass balance simulations suggest that the formation of porphyry copper deposits requires fast accumulation of large magma volumes, which are also capable of destroying those deposits if magmas erupt.

Metallogeny in the Bangong–Nujiang belt, central Tibet, China: A review

Frontiers in Earth Science, 2023
The Bangong–Nujiang metallogenic belt consists of scattered Tethyan oceanic blocks, mainly distributed underneath the margins of the Qiangtang and Lhasa terranes in central Tibet.

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Oxidized sulfur-rich arc magmas formed porphyry Cu deposits by 1.88 Ga

Nature Communications, 2021
Tectonomagmatic conditions in the Precambrian were hypothesized to be unfavorable for porphyry Cu deposit formation. Here, the authors show that metallogenic processes typify Phanerozoic porphyry Cu deposits operated by ~1.88 Ga, reflecting modification ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

The copper polymetallic deposits and resource potential in the Tibet Plateau

China Geology, 2021
: Many large and super-large copper deposits have been discovered and explored in the Tibet Plateau, which makes it the most important copper resource reserve and development base in China. Based on the work of the research team, the paper summarizes the
